The effect of an amorphous silica matrix on the structure and charge distribution of silver nanoparticles is investigated by dispersion-corrected DFT calculations. A matrix-induced electron loss of silver nanoparticles is reported.
Silver nanoparticles (AgNPs) are widely used in the health-care sector and industrial applications because of their outstanding antibacterial activity. This bactericidal effect is mainly attributed to the release of Ag+ ions in an aqueous medium, the first step of which is the dissolution of the AgNP via the oxidation of its surface by O2. With...

Many applications as optical spectroscopy, photothermal therapy, photovoltaics or photocatalysis take advantage of localized surface plasmon resonance of noble metal nanoparticles. Among them, Ag nanoparticles are multi-functionnal nano-objects that can be used as efficient plasmonic antennae but also as electron reservoirs for charge transfer...
